SpaceX had reset the countdown clock for its next human spaceflight, but a NASA decision has forced another delay of the private Axiom Space Ax-4 mission to the International Space Station.

With the launch of Axiom Mission 4 being delayed again, SpaceX is set to launch a Starlink mission during the early hours of Sunday from Florida.

NASA wants to evaluate recent efforts to stop a small but persistent air leak in the Russian segment of the space station.
